It is indeed annoying when people keep spamming the wrong chat channel for something.
The funny thing I observed, though, is that people will directly tell you to use the proper channel when using world for trade/LFP, but when people try recruiting for arena no one cares.
I believe, just as the OP posted, this belongs to LFP as well as you are looking for people (->LFP, or at least one way to interpret the abbreviation).
But to be honest, sometimes people are a tad bit too sensitive or chat-police like when it comes to telling people off when they use the wrong chat.
I think if you post once in a wrong chat then there is no need to start off against this person, as it can always happen that you mistakenly used the wrong shortcut to the chat.
Yet, people start yelling at the 'culprits', sometimes even in a rude manner.
I have even seen the 'culprit' apologize, saying they wc'ed by accident and the response they got was "yea right I will watch you".
About giving GS'es powers to mute, I agree with Salad that this should not be done because of the risk of abusing it.
However, I wish there was a tiny slap on the hands if there is a repeated offense
Not just once or twice, but if a person clearly is using the wrong chat puposely.
On a lighter note: isay37 your signature is too big.
